LUBFIIOATOR.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Ap li ati fil d December 14, 1904, Serial No. 236,884.

T0 or. whom, it may concern:

Be it known that we, EDWARD-A. HENRY and ORLYN A. SNEED, citizens of theUnited States, and residents of Joplin, in the county of Jasper andState of Missouri, have invented a new and Improved Lubricator, of whichthe following is a full, clear, and exact description.

Our invention relates to lubricators and admits of general use, but isof peculiar service upon steam-engines and analogous motors in which itis desired that the feed of the lubricant shall have a relation to theflow of steam or of some other aeriform body.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi catecorresponding parts in both the figures.

Figure 1 is a side elevation of our device and the connections usedtherewith, and Fig. 2 is a front elevation of the spider 11 removed fromthe valve-casing.

The steam-line is shown at 3 and preferably leads downward to the memberto be lubricated forinstance, a steam-cylinder. Fitted steam-tight intothe steam-line 3 is a bushing 4:, which encircles and holds in positiona cylindrical member 5, provided with a cylindrical passage 6 coaxialtherewith. A valve 7 is seated at one end of the passage 6 and isprovided with a stem 8, loosely encircled by a spiral compression-spring9. A duct 10 leads obliquely downward from the passage 6. A spider 11 ismounted Within the passage 6 and is provided with passages 12communicating with the passage 6. The spider 11 is also provided with acentral slideway 13, which is engaged by the slidable valve-stem 8. Anecklt, constituting a part of a globevalve 20, engages the casing 5 andserves to hold the spider 11 in position, the casing 5' being threadedfor the purpose. The spider 11 and the neck 14: are severally threadedand screwed into the cylindrical casing 5. Mounted upon a pivot 15 is acam 16, havinga plate,

17 integral therewith. This plate carries a door 18, secured upon it bymeans of a rivet 19. The globe-valve 20 is controllable by the usualconstruction. The steam connections for the lubricator consist of thepipe 26, globe-valve 27, pipe 28, condensing-chamber 29, valve 30, andhandle 31, these parts being preferably of ordinary construction.

The normal position of the parts when steam is not passing through thesteam-line 3 is indicated by full lines in Fig; 1. When, however, steamis caused to flow through the steam-line 3, it impinges against the door18,

which is thereupon bent downward, as indicated by dotted lines inFig. 1. The momentum of the steam jet passing through the steam-linegoverns the degree of angular movement executed by the door 18, and consequently governs the position assumed by the cam 16 and the valve-stem8. The result is that the duct 10 is opened to a greater or lesserextent by the displacement of the valve 7 as the latter moves back so asto compress the spring 9. When the duct 10 is open, the lubricant canflow from the passage 6 through the duct 10 into the steam-line 8 andthence conveyed to the point where it may be needed. When, however, theflow of steam through the steam-line ceases, the pressure of the spring9 seats the valve 7, closes the duct 10, and thus stops the further flowof the lubricant.

Having thus described our invention, we claimas new and desire to secureby Letters Patent 1. In alubricator, the combination of a normallyclosed valve for feeding a lubricant, a door connected with said valve,and means forcausing an aeriform body to impinge upon said door so as toopen said valve.

2. In a lubricator, the combination of a movable member, means fordirecting upon the same a moving jet of an aeriform body, a valveconnected with said member and adapted to be opened by movementsthereof, and means for feeding a lubricant to said valve.

3. The combination of a steam-line, a door hinged therein and adapted tomove by the impact of a steam-current thereupon, a cam connected withsaid door, a cylindrical member disposed adjacent to said cam andprovided with a valve-seat and with a duct adjacent to said valve-seat,a valve member mounted within said cylindrical member and adapted toclose said duct, means for normally retaining said valve inapredeterrnined position, and means for feeding a lubricant into saidcylindrical member.

4:. The combination of a spring-controlled valve for controlling theflow of a lubricant, a cam adapted to engage said valve so as to unseatthe same, and a member controllable by a moving mass of an aeriforrnbody for shifting the position of said door.

In testimony whereof we have signed our names to this specification 1nthe presence of two subscriblng Witnesses.
